Nokia's patent catalogue covers technology that reduces the need for hardware components in a phone, conserves battery life and increases radio reception, among other features.

Nokia has signed a multi-year smartphone patent licence deal with China's Huawei -- its arch-rival in the networks business -- giving it royalty agreements with all of the world's largest handset makers. The Finnish company said on Thursday it would start booking revenue, including a one-off catch-up payment, from the fourth quarter. The two companies did not provide further financial details of the agreement.

Nokia has recently struck licensing deals with handset makers including Apple, Samsung Electronics, LG and Xiaomi. Nokia's patent catalogue covers technology that reduces the need for hardware components in a phone, conserves battery life and increases radio reception, among other features. More than 90 percent of Nokia's revenue comes from telecoms network equipment, but the licensing payments are highly profitable which is especially welcome as the network business is suffering an industry-wide slump.

Nokia's shares rose 2.1 percent by 1415 GMT but are down around 14 percent over the year as a whole. "It's a significant deal because Nokia now has agreements with all the big phone makers... The network market will remain tough, but the growing patent revenue will compensate for it," said analyst Mikael Rautanen from research firm Inderes, which holds a "buy" rating on the stock. He said revenue from the Huawei deal would be smaller than from Apple, which he estimated to be around 250 million euros ($297 million) annually.

"The (Huawei) ballpark (figure) could be somewhere over 100 million euros annually," he said, adding that he believed the additional catch-up payment would be considerable. The two companies are strong rivals in the global telecoms equipment market. Nokia, which a decade ago was the world's largest cellphone maker, withdrew from the handset market in 2014 but remains a major licensor of wireless technology, as well as a supplier of mobile and fixed-line network gear.

Huawei is the biggest maker of telecoms equipment by revenue and the world's third-largest maker of smartphones. Early last year Nokia struck a patent licensing deal with Samsung on terms that disappointed its investors. But earlier this year it signed a broad cross-licensing deal with Apple, which was seen as favourable to Nokia. In October, Nokia shares lost almost a fifth of their value after the company reported a sharp drop in net earnings, citing weak market and internal problems.
